The modular machine as defined in claim 1 wherein said base frame side members being hollow and said axle assembly comprising an integral unit including a hub and sprocket, said hub being releasably mounted to a base frame side member with said sprocket extending into the interior of the side member, said fluid motor being drivingly connected to said sprocket.
Claim 4
Dependent Claim
88 words
The modular machine as defined in claim 1 wherein said base frame assembly including at least one fluid pump and a control valve connected between said fluid pump and fluid motor, said operator's control station including control handles which are operatively connected to said control valve for permitting an operator to control forward, reverse and steering movements of the machine, said operator's control station being removable from said base frame assembly thereby permitting complete access to said fluid motor, fluid pump, and control valve for servicing or repair.
